IMPROVEMENT IN DOORS.

Specification forming part of Letters Patent No. 116,010, dated J une 20, 1871.

To all whom it may concern; 7

Be it known that I, BENJAMIN BARKER, of Belfast, in the county of Waldo and State of Maine, have invented anew and useful Improvement in Doors; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein g had to the accompanying drawing forming part-of this specification.

, This invention relates to improvements in outside doors of houses and other buildings; and it consists in having vertical grooves at the joints between the doors and frames; also between the two doors when two are used,

leading into a horizontal groove along the side and G, the sill. 1) represents vertical grooves in the door-posts, one at each corner of the rabbet-s, in which the doors close when shut. E is a vertical groove between the doors,'part- 1y formed in each. F is a horizontal groove in the upper side of the sill under the doors, ex-

tending from end to end, into which the said vertical grooves lead; and F is an escape-passage froin groo've E to the outside under the door-step, or to any convenient place for the discharge of the water..

The rain-water, snow, or air driven into the cracks by the wind will be arrested in the spaces formed by these vertical grooves, and

will fall to the groove F and thence escape to the outside, and be thereby prevented from passing through into the building.

The grooves D may be partly or wholly formed in the door, if preferred.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- In combination with an ordinarily-apertured sill, F O, the door A, having vertical grooves D E D at the joints thereof to form channels for the reception of air, water, and dust, and

its guidance into the discharge-channel F of the sill. BENJAMIN F. BARKER.
